An automatic speed control system that provides desired watercraft velocity over land. Display data is converted into a format that emulates the first color gamut. The stereoscopic video display module outputs video for left and right eyes. The method includes storing the objects and corresponding attributes in a persistent element store. The insert may have containment and absorption features that prevent soiling of the outer cover by the wearer’s exudates, so that the outer cover may be reused after an exudation event and change of inserts. The collected timing data may be processed to derive predictions for processing times on a profile-by-profile basis.
